The Fike Micromist ® fire suppression system produces a fine mist to extinguish fires quickly with very little residual water. For typical water spray system design density of spray typically ranges from 6.1 (L/min)/m2 to 20.4 (L/min)/m2. For example, in a deluge application of similar hazards, a water mist system uses up to 90 percent less water compared to sprinklers, and on a light hazard it uses up to 50 percent less water. References FOGTEC is an extinguishing system using pure water, effectively fights burning liquids or solids and requires very low volumes of water. Alternative systems 10.1 Automatic sprinkler systems 11. Since 1996, NFPA's rules for water mist systems have been available in NFPA 750: Standard on Water Mist Fire Protection Systems.
